1. Trigonometry: Sine and Cosine
Sine and cosine are basic trigonometric functions that are used to solve for the angles and sides of triangles. Review trigonometry concepts and learn about the mnemonic used for sine, cosine, and tangent functions.
2. Evaluating Trigonometric Functions With a Scientific Calculator
Trigonometric functions are often used to model the world around us. In this lesson, review the definition of trigonometric functions and inverse trigonometric functions, and look at how to use a scientific calculator to evaluate them.
3. Solving Right Triangles Using Trigonometry & the Pythagorean Theorem
The Pythagorean Theorem is one of the most well-known and useful math equations. Its simple form and abundant uses make it one of the most helpful processes to learn in math. In this lesson, learn how to solve right triangles using the Pythagorean Theorem.
4. Using Trigonometry to Work With Vectors
Lots of physical quantities, like force, displacement, and velocity, are vectors. In this lesson, learn how to use trigonometry to work with vectors and get a chance to practice adding various kinds of vectors.
